By the time Gen X and Y hit retirement it looks like we’ll be getting about 3/4 of the amount people are receiving now. Factoring in inflation, that means we’ll have roughly enough every month to fill up the gas tank and buy some groceries. If you’re not putting away at least 10% of your income into an investment earning a rate of 3% or greater you will be in trouble.

Unless, of course, you plan to work until the day you die. In which case, don’t worry about it.
